The information on the differences between LCCS and Stratus are a bit buried -- apologize for that. However, it's documented here on our Product FAQs:
What is the relationship between Adobe Stratus and Live Cycle Collaboration Services – they sound like the same product? Adobe Stratus on Adobe Labs is a preview technology for Peer Assisted Networking using RTMFP for media and data delivery. LCCS offers similar functionality to Stratus but has a commercial option with a pricing model that companies can use to integrate RTMFP into their business solutions today. Most importantly, Stratus will not be a commercially available offering. For more information about Stratus, visit http://labs.adobe.com/technologies/stratus/
